The Messier 3 Cluster (メシエ3球状星団) Messier 3

During the rainy season, I could see the stars for the first time in two weeks.
Even though I had 90% Moon, it was better than doing nothing. I photographed Messier 3, which is far from the moon, thinking it would be able to cope with the moon's light pollution.
The stars around this cluster are distinctive in that they draw an arc like a crown, and there are some streams of stars lined up in a straight line.
Also, there are some small silver particles behind this cluster, but they are difficult to find among the star clusters. The easiest to understand is probably the galaxy in the south.
